  1. Extinction of fear in rats does not depend on long-term habituation Stephanie Damas, Cheryl Novak, Brian L. Thomas Baldwin-Wallace College

  2. Introduction • NS  No particular response bee • NS + US  UR bee sting pain • CS  CR bee anticipatory fear/avoidance (Pavlov, 1928). • Fear conditioning (Estes & Skinner, 1941). • EU: CS not predict /US (Rauhut, Thomas, & Ayres, 2001).

  3. Purpose • Is relapse prevented in the EU procedure because the rats become habituated to the US? • Is there a possible double dissociation, similar levels of US habituation with varying relapse and similar levels of relapse with varying US habituation?

  4. Method • Procedure

  5. Results: Renewal

  6. Results: Reinstatement/Habituation

  7. Conclusions • The EU procedure is not dependent on US habituation. • Supports double-dissociation • Habituation strong in 2+ and 4+ groups, but CU groups with habituation relapsed significantly • Procedure groups, for example EU groups with 1, 2, and 4 USs, did not differ in renewal, but did differ in US habituation
